This is “The Perc”, the third instrument present in our online portal. The Perc is based on the same algorithm for mutual synchronization used in “The Pulse” instrument. It’s inspired by biological systems and adopted for sound creation by Stratos Bichakis. As a liberation from the locked groove that much of the music seems to have fallen into, The Perc (alike The Pulse) suggests a playful alternative to creatively explore the potential of the fragile states beyond fierce synchronicity and expand the temporal polyphony.

This is the online version of the “The Pendulum” Instrument. It’s a drone synthesizer which was specifically designed for the installation @ctmfestival Any changes done on the digital instrument would be perceived on the space @hauberlin and vice versa; changes on the physical pendulum movement would be perceived on the online instrument sound and interface. On top of that, the instrument uses web sockets technology, allowing users to jam inter-remotely in real time.

Pulse is an instrument based on an algorithm for mutual synchronization, inspired by biological systems and adopted for sound creation by Stratos Bichakis (@stratos_bichakis ). Pulse is inviting the user to explore the space in between chaos and emergent order, unity and diversity, by adjusting the level of entrainment of each different node’s listen parameter. ‘Mutual synchronization occurs in many populations of biological oscillators. Examples include male fireflies in south east Asia; pacemaker cells of the heart; networks of neurons in the circadian pacemaker and hippocampus; insulin-secreting cells of the pancreas; crickets that chirp in unison and women whose menstrual periods become mutually synchronized.’ Synchronization of pulse coupled biological oscillators. Renato. E.Mirollo and Steven H.Strogatz. Society of Industrial and applied Mathemathics. 1990. In both digital and analog music creation systems, rhythmic unison is not even questioned. Furthermore, many technological companies have built their reputation exactly by offering to the users, masterful features to guarantee rhythmic coherence by any means. As a liberation from the locked groove that much of the music seems to have fallen into, Pulse suggests a playful alternative to creatively explore the potential of the fragile states beyond fierce synchronicity and expand the temporal polyphony.

Parallell to the physical instruments created for the installation @ctmfestival at @hauberlin , we created an online portal where you could access and play with different online instruments. By using web sockets technology, these online instruments allowed you to directly control and condition the sound of the physical installation but also to jam inter-remotely with any online participant; any change done through these instruments would be perceived in real time both online and in the installation space.

This is “The Pendulum”, the second physical instrument created for the CC0 installation @ctmfestival 2023. It’s comprised of an accelerometer, projector, stainless steel chain, metal frame on bearings, OSC network, socket.io network, p5.js and Max msp through RNBO. Connected through an OSC network, the pendulum represented a physical interaction point of the online version of the instrument. Any changes done on the digital instrument would be perceived on the space @hauberlin and vice versa, changes on the pendulum movement would be perceived on the online instrument sound and interface.

This is “The Forum”, one of the instruments created for the CC0 installation @ctmfestival 2023. The Forum is a public domain of reflection. Using a local network of microphones connected through a Max patch created by @cerionimusic , the forum takes your voice and stores it in a pool of collective memories which then plays back in a generative fashion using the multichannel panels/transducers speakers as output. “In the final stage of his “liberation” and emancipation through the networks, screens and technologies, the modern individual becomes a fractal subject, both subdivisible to infinity and indivisible, closed on himself and doomed to endless identity. In a sense, the perfect subject, the subject without other-, whose individuation is not at all contradictory with mass status.” Jean Beaudrillard - Instrument credits: Martin Lundfall: concept, production Massimiliano Cerioni: concept, instrument sound development (RNBO/MAX) Miguel La Corte: concept, production.

Pictures by @jamie.jar [4] You can also see “The Forum” in action through this video; users input a collection of different pop songs to the instrument’s memory. The instrument then reproduces these in a generative fashion, encouraging the public to abruptly switch from a state of “expression” to a state of “listening”.

By November 2022, we created an open call for the development of the exhibition, in the frame of a hackathon. The development of instruments of collective creation was set as the core structure of the exhibition; the hackathon leveraged on the newly announced RNBO tool by @c74connect as the core infrastructure for the instruments to be developed upon. It is within this context where CC0 (Collective Control 0) was created. Through a process of collaboration in the form of a hackathon, CC0 emerges as a collection of instruments for collective creation. Evoking tools and systems of social organization, 3 instruments were carefully composed: “The Forum, Pendulum and Pulse”. [1] Hackathon distribution poster

CC0 was initiated thanks to support from the initiative »Prototyping Sonic Institutions« organised by Black Swan and CTM Festival 2022. @blackswan_dao is a Berlin-based collective experimenting in horizontal and decentralised, infrastructure and governance. Within May 2022, Black Swan hosted the workshop titled “prototyping sonic institutions” in collaboration with CTM 2022 where a number of resources were pledged by various partners, to allow for the realisation of a music/sound related project. Participants selected via open call then proposed their own project ideas to the group, or simply indicated a wish to experiment in collective decision-making. Using Black Swans’s digital toolkit, including a quadratic voting application known as Cygnet, participants collectively decided how to disseminate and allocate the resources pledged to their projects. By June 2022, after a voting round utilizing the quadratic voting tool, successful applications were announced. Thanks to the resources pledged by the CTM 2022 x Black Swan workshop, the Participative Audio Lab (PAL) was then granted a commission for developing an exhibition at HAU2 within the context of CTM Festival 2023.

About 1 year ago we concluded our inauguration exhibition titled <<CC0: Collective Control Zero>> within @ctmfestival 2023 in @hauberlin - “No one knows everything, everyone knows something, and all knowledge resides in humanity… New communications systems should provide community members with the means to coordinate their interactions within the same virtual universe of knowledge.” Collective Intelligence — Pierre Lévy, 1994 - *CC0 (Collective Control 0)* is a system for live collective composition consisting of three different instruments: “The Forum, Pendulum, and Pulse”. These were conceived and developed through an open creative process in the shape of a hackathon. The installation was designed to enable distributed control to the public through these instruments which directly condition the system’s motion, sound, and structure. On 31.02.23 after 2 months of collective making, CC0 went live within the context of CTM festival 2023; public participants were thus allowed to take part in a live interdependent composition accessible online or within HAU2 in Berlin. You can still access the online instruments of CCO here: 🔗 Within the next few days we will be showing some of the development process of this exhibition as well as the outcome instruments. - PHOTOS INFO: [1] Exhibition info poster in @hauberlin [2] CC0 Online instruments website [3] “Perc” instrument [4] “Pendulum” instrument [5] “Pulse” instrument [6] “The Forum” instrument panels [7] “The Pendulum” physical instrument [8] HAU2 info poster [9] Project booklet *DM IF YOU WANT ONE! :)* [10] Intro room

CC0 (Collective Control 0) is a system for live collective composition existing in Berlin within HAU2 and also anywhere through the portal participativeaudiolab.com It has been designed to enable distributed control to the public through physical and digital instruments which directly condition the system’s motion, sound, and structure.

CC0 marks the inauguration of PAL (Participative Audio Lab), a initiative aimed at the development of open-source tools to allow artists to create and distribute their own participative musical experiences. On a broader scale, PAL aims to harvest a culture of open creation.
